Abstract (en)
[origin: WO9210366A1] A film combination has a pair of polymeric substrate films. At least one surface of each has a surface free energy of at least 35 dynes/cm and a primer coating on each. Each primer coating has a layer of poly(vinylalcohol) containing a cross-linking means. Each film of the pair is positioned with the poly(vinylalcohol) layers in intimate contacting relationship before any substantial cross-linking occurs.
Abstract (fr)
Pellicule combinée comportant une paire de pellicules formées par un substrat polymère. L'une des surfaces de chaque pellicule au moins, possède une énergie superficielle libre d'au moins 35 dynes/cm et chaque pellicule est revêtue d'une première couche. Chaque première couche comporte une couche d'alcool polyvinylique contenant un moyen de réticulation. Chacune des pellicules formant la paire est placée en contact étroit avec les couches d'alcool polyvinylique, avant l'apparition d'une réticulation importante.
